Topic: STS Turn module (Read 1520 times)

Anyone installed the self-cancelling turn signal module? I'm interested, just not sure where all the wiring for this would be. I'm guessing it's easiest to access in the left fairing. In reality, it's only 8 wires to tap into.

It's well covered in this thread. It works fantastic. After riding 1200 miles with it so far, I wouldn't want to do without it. Being on a COG group ride for the third time this year yesterday, there are a few others that could use it.

For those looking into this, here's what I"ll be using based on wiring diagrams and where others have tapped into the handlebar wiring up by the forks: Wiring STS ModuleWire Module to bike Module to Handlebar Grey Yellow White Right handlebarRred/green Blue Brown (ornage after harness)Green Green Purple Left Handlebar Power + RedPower - Blackfemale to bike Male to switches

There are no +12 Volt and ground leads in the harness that comes from the turn signal module. I have a fuse block in the tool case and had spare wires to the front of the bike that I used for this module.

No worries though. There are forward +12V and ground accessory leads located in the rubber boot on the left hand side under the fairing glove box 2010 and newer. They are available for use. Fred Harmon has some detailed photos, here that should help. Obviously look for the front leads on this page.

That's what I tied into, the accessory leads up there. Just hoping to clean it up with all the leads going into to the harness. I found a ground (Black with yellow) in the harness and figured there had to be a switched power lead as well. Tapped into a couple to check and have had no luck yet. Plus I already have a CB and USB port tied into the accessory leads and I don't want to put too much draw on it and blow the fuse.

Thanks for the reply.

Just curious, how are you running the leads from the back of the bike forward? Are you going under the fuel tank or just going behind the side fairings?

Self canceling on lane changes at 70 mph has proven very unreliable so far. Worked maybe 1 out of 5 tries. Have you had any experiences with that you can share?

And thanks to Fred Harmon for having pictures of everything available to us!

For the lane changes, I find it works if you just put a little more emphasis on the turn. That works every time. A slow gradual lane change over a long distance is not going to turn off the signal. However, it will turn off after 12-15 seconds which is still a bonus in my book. I think you agree it works on all other turns that are not lane changes.

Here are the details for how I routed the wires and installed my fuse block in the useless tool box.

Those power leads and that rubber boot covering them have been present on all C-14's Steve, from the '08 onward. The change on the 2nd Gen. models (2010 and on) is that the current rating went from 10 amps available to the user to 5 amps because the heated handgrips are on that same circuit.

Haa we are both correct since I did say it was under the glove box which is 2010 and newer. I wasn't sure about the Gen 1's having the leads, but now that you mention it, I totally recall that being the case with the leads and different power rating.

Well, I hope you know me well enough to know that I am not trying to be 'right', just pass along the most correct info. And of course I was not trying to disparage you in any way. Hey, I get corrected all the time and am almost always grateful (there is this one gentleman I know, extremely smart but he just rubs [the entire planet] the wrong way, so when he corrects, it just grates....), again not a matter of who is 'right' but getting the correct info. out there.

Both the front and rear aux. leads have always been provided in all C-14's. 4mm (or 5/32" if you prefer) bullet connectors, the male on the bike being ground with the covered female being +12.

Back to the topic at hand, this does look like a slick little gadget from reading what is printed on the website. Much, much more sophisticated than the older, distance- traveled turn signal cancelers of the late 70's. Although honestly, any automatic turn signal canceler, even the old types, might just save a rider's life.

Thanks for posting your results. Wait till you ride with it for a few weeks. They couldn’t pay you to give it back since it works so well. It’s great to finally be infallible with the turn signal. And a heck of a lot safer too.
